Title: Method for judging transplantation suitability
Inventor: INOIE MASUKAZU
IPC: G01N33/48
Filed: 2001-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for judging transplantation suitability, by which the transplantation suitability can easily be judged. SOLUTION: This method for judging the transplantation suitability comprises using a cultured tissue as a measurement target in the tissue state as such without subjecting the cultured tissue to a dispersing treatment, treating the cultured tissue of measurement target with an enzymatic activity-measuring reagent which can be converted into a substance itself capable of being spectroscopically measured by a reaction with an intracellular enzyme in the cultured tissue, spectroscopically determining the converted substance, and then judging the transplantation propriety of the cultured tissue on the basis of the determination result.  Since the cultured tissue is used as the measurement target in the tissue state without subjected to the dispersion treatment in the method for judging the transplantation suitability, a damage caused by the dispersion treatment is not added to the measurement target. The activity of the intracellular enzyme in the cultured tissue is determined with the enzymatic activity-measuring reagent, and the enzymatic activity relates to the number of living cells. Therefore, a living cell rate can consequently be obtained as a numerical value, thus saving a labor for counting the number of the cells under a microscope.

Filed: 2001-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a rice polisher for removing bran from the surface of white rice which can always introduce air from an intake port and reduce noise generated by rice polishing with a low-cost structure. SOLUTION: After feeding a prescribed amount of the white rice 1 into an accommodation container 6, a rice polishing blade 31 is driven by a driving means 33 to start a rice polishing process. In the rice polishing process, a cycle where the white rice 1 goes up in the rice accommodation container 6 and moves to the approximate center of the rice accommodation container 6 is repeated, and the bran 4 is scraped from the white rice 1 to be discharged outside of the rice accommodation container 6. At this time, air is ventilated by a recovery means 38 to an air intake port 40, the rice accommodation container 6, a bran bag 39, the recovery means 38, and an air exhaust port 41 through an air ventilation passage 42. The bran 4 produced during the rice polishing process is collected in the bran bag 39 by this air flow.  The noise generated by rice polishing goes out from the air intake port 40 to the outside of the rice polisher 30, and then moves to directions other than an approximate forward direction of the rice polisher 30 by the action of a shielding plate 43 integrally formed with the rice polisher 30.
